CARBON ALLOTROPES The Same & Not the Same A computer program module developed by Matthew A. Armfield from Deerfield High School for northwest Universitys Nanoscale Science and Engineering Center through the 2005 enquiry watch for Teachers Program Topic Overview Content in a Nutshell Allotropes ar compounds that make up in mildews with different chemical structures. Some common examples of allotropes are phosphorus (white or yellow, red, and faint / purple), oxygen (O2 and O3) and in the end carbon paper (diamond, graphite, fullerenes and carbon nanotubes, or CNTs). The specific cross of carbon, and its bind to surrounding atoms willing steady down which allotrope carbon will assume. Carbon with sp3 hybridization will earn a tetrahedral lattice, therefrom giving rise to diamond. Carbon with sp2 hybridization will form either graphite (arranged in hexangular sheets), buckyball (60 carbon atoms forming a sphere), or carbon nanotubes (long dig out tubes of carbon ) depending on the conditions in which it is formed. Diamond and graphite have been cognize since antiquated times (the word diamond comes from the ancient greek, adamas means im feasible to tame) but buckyball and CNTs have solely been spy within the last twenty years, and are just straightway beginning to be characterized. Buckminsterfullerene, C60, was discovered by Kroto, Smalley and coworkers in 1985, although its come-at-able existence had been discussed by other chemists years earlier. For the first just a(prenominal) years after its discovery, it was a laboratory curiosity. However, when it was discovered that unmistakable amounts of C60 were formed by heating graphite rods under conservatively controlled conditions, research on this material took off. One of the first questions indwelling chemists asked about it was, What are its chemical properties? Since all of the carbons on buckminsterfullerene are sp2 hybridized, C60 could be handle benzene, C6H6, whic h is an aromatic molecule, or wish ethylene! , which...If you want to get a full essay, order it on our website: OrderEssay.net
